The SMOKE ancillary files available in the $GE_DAT directory are the most likely files for you to be able to use directly or adapt to your modeling case. Table 3.2, “Default SMOKE ancillary files except inventory and speciation files” describes all of these files except for the speciation profile files and speciation cross-reference files, which are provided in separately in Table 3.3, “Default SMOKE ancillary files for speciation in $SMKDAT/ge_dat ($GE_DAT)”.

| abmgpro.m3.040402.us36+can+mex.txt | AGPRO, BGPRO, MGPRO |
U.S. 36-km cell surrogates with Lambert projection center (40 degrees latitude, -100 degrees longitude), upper meridian at 30 degrees, and lower meridian at 60 degrees. Lower left grid location at (-2196 km, -1692 km) with 132 cells in the x-direction and 90 cells in the y-direction. Created based on EPA national surrogate data for the EPA’s CMAQ “Proof of Concept” project plus Mexican population surrogate data added in 2001 from the Western Regional Air Partnership (WRAP) Regional Modeling Center (RMC), developed by MCNC. These pertain to the use of 1996 U.S. emissions and will not apply to the 1999 NEI. |
| amgref.m3.us+mex.txt | AGREF, MGREF |
U.S. and Canadian, spatial surrogate cross-reference from EPA web site: http://www.epa.gov/ttn/chief/emch/spatial/ from 3/5/02. Mexican population surrogate assigned to all Mexican SCCs for WRAP RMC. These pertain to the use of 1996 U.S. emissions and will not apply to the 1999 NEI. |
| amptpro.m3.us+can.txt | ATPRO, MTPRO, PTPRO | U.S. temporal profiles from EPA web site: http://www.epa.gov/ttn/chief/emch/temporal/ from 4/29/02 for monthly profiles and 12/14/2000 for weekly and diurnal profiles. Canadian profiles added by MCNC for EPA’s CMAQ “Proof of Concept” project. North Carolina Department of Environment and Natural Resources (DENR) on-road mobile profiles added for default road-class-specific profiles. These profiles have not yet been tested with the 1999 NEI. |

File created with SMOKE’s Metscan utility by MCNC for national 36-km grid (see description of file abmgpro.m3.040402.us36+can+mex.txt for grid parameters). |
| costcy.txt | COSTCY | Country, state, and county codes file. Provided by EPA/ORD via Dyntel circa 1998 and updated with Miami-Dade revisions. Will work for 1996, 1999, and later inventories. Includes time zone and Daylight Saving Time status information. Country codes added by MCNC for default SMOKE countries. |
| GRIDDESC | GRIDDESC | Grid descriptions file with numerous grid descriptions for EPA/ORD, EPA/OAQPS, RPO, and state modeling domains. An unlimited number of domains can be added to this file. |

The file format suggests that this file could be set up by state or county, but SMOKE cannot currently use the file in this way. Therefore, the state/county code field should always be filled with a zero. |

The last type of ancillary files we discuss in this section are speciation profile files and speciation cross-reference files. There are many speciation files that are needed for SMOKE because of the large number of models and chemical mechanisms that SMOKE supports. Table 3.3, “Default SMOKE ancillary files for speciation in $SMKDAT/ge_dat ($GE_DAT)” summarizes these files and the many components that they have. The letters in the cells within the “Description” column indicate which major components are included by the GSPRO and GSREF files. These cells need supporting explanations, which are provided in the bulleted list below.
Profile 0000: Contains pass-through profiles for CO, NH3, SO2, and PMC; also splits NOx into 90% NO and 10% NO2. Includes the profile for BEIS2 speciation, including creating TERPB from TERP for CMAQ files that use this profile.
BEIS3: Includes the BEIS3 profiles prepared by Tom Pierce at EPA/ORD. The biogenic-only speciation profile files are not associated with a speciation cross-reference file because biogenic processing uses only one profile and does not need a speciation cross-reference file.
CMAQ CB4: Includes TOG profiles and SCC assignments from EPA web site (3/8/02), http://www.epa.gov/ttn/chief/emch/speciation/. Cross-reference entries are for VOC, because VOC is anticipated in the inventory and the inventory pollutant is what is used to assign profiles by SCC.
CMAQ PM: Includes PM2.5 profiles and SCC assignments from EPA web site (3/8/02), http://www.epa.gov/ttn/chief/emch/speciation/
CMAQ CB4tx1: CMAQ CB4 toxics (version 1) TOG profiles and VOC SCC assignments to be used when integrating toxics VOC with criteria inventory for on-road mobile sources. Because changes are being made to the research version 1 of CB4 toxics, it is expected that users will have to create new CB4 toxics profiles for all source categories. TOG profiles are labeled with profile codes ending in “A” to identify them as different from standard profiles. They were developed by Jerry Gipson at EPA/ORD and can be used only for the “no-integrate” case, to drop mass of acetaldehyde, 1,3-butadiene, formaldehyde, and acrolein (all explicit CMAQ toxics). Benzene is mapped to both CB4 species (PAR and NR) and to special BENZENE species, which doubles the mass of benzene output by SMOKE. Added to file by Marc Houyoux, MCNC. Cross-reference entries are for VOC, because VOC is anticipated in the inventory and the inventory pollutant is what is used to assign profiles by SCC.
Toxics: Includes toxics mapped to CB4 species using profile 0000. Developed by Jerry Gipson at EPA/ORD. Added to file by Marc Houyoux, MCNC.
RADM: RADM2 TOG profiles and VOC SCC assignments (which are the same as assignments for CB4), origin unknown. Cannot be used with the toxics inventories.
SAPRC99: All TOG speciation profiles for the SAPRC99 mechanism. TOG profiles provided by EPA/ORD, circa 2001. Never tested by MCNC or CEP for SMOKE release. Cannot be used with the toxics inventories.
REMSAD6: REMSAD version 6 PM2.5 speciation profiles from ENVIRON and EPA. The PM2.5 profiles are the same as those for CMAQ except that they use different species names. Cannot be used with the toxics inventories. VOC profiles pass through VOC using average molecular weight of 16, as needed by REMSAD version 6.
REMSAD7: Created by CEP July 11, 2003. VOC profiles created from CMAQ TOG profiles as described in header for XYL and TOL (used for REMSAD SOA computation only). These are actual VOC profiles and therefore do not require the VOC-to-TOG conversion. VOC-to-CARB profiles added based on CARB = 0.03 x VOC. Also contains pass-through profile for cadmium (CD). PM2.5 profiles are the same as those in the REMSAD6 file, which are the same profiles as for CMAQ, but they use different species names.
SO2-SULF: Includes point-source SO2 profiles for creating a SULF species from SO2; mass is intentionally not conserved (SULF mass is added to SO2 mass). Profiles from Ron Ryan, EPA/OAQPS, 2001.
HG: Mercury profiles and assignments created by Marc Houyoux, CEP, based on data provided in 2003 by Madeleine Strum, EPA/OAQPS. These HG profiles are based on 1996 inventory and need to be updated to account for new MACT codes and updated data. For REMSAD, molecular weight for HG species set to 201 as per REMSAD documentation, which is not the same as CMAQ HG. A different default mercury profile is used for point sources than for nonpoint sources. For on-road mobile, a single mercury profile that maps HGSUM to the mercury model species is included.
MOBILE6: Includes MOBILE6 profiles as per EPA/OTAQ, 2002. These include process-specific assignments needed for both MOBILE5 and MOBILE6 emission processes (e.g., exhaust starting, evaporative).
NONHAP: Includes NONHAPTOG and NONHAPVOC profiles and toxic pollutant profiles created by Jerry Gipson, EPA/ORD, and added to file by Marc Houyoux, MCNC. Uses NONHAPVOC/NONHAPTOG definitions from EPA, 2002. Extra pollutants included erroneously for nonroad-mobile sources: CHLOROBENZN, METHANOL, MEK, and PHENOL. Mass for these pollutants has been dropped from NONHAPVOC/NONHAPTOG profiles when it should not have been (the profiles still conserve mass because they were normalized after removing the appropriate HAPs, it is simply that none of the mass pertains to the above pollutants; this error is expected to be very small since the above pollutants account for less than 1% of the TOG for nonroad mobile sources).
